Project Description

I am looking to work with a developer who can create a program that loops through columns in a spreadsheet and aggregate data in a specific way.

The input will be a CSV spreadsheet dataset and the output must be a CSV spreadsheet dataset. I am looking for the language best able to handle up to one million spreadsheet rows and up to 15 columns for a total of 15,000,000 elements, and the program will have to loop through this data set multiple times.

The program should:

1. Parse through the input dataset to build a list of unique elements, based on a specific rule.
2. Loop through the initial input dataset and create a sum total of all data points associated with each element from the list built in step 1.
3. Return a new data set of sum totaled data.
